Precipitation is the key determinant of topsoil δ15N values in southern Patagonia's semiarid rangelands
(Soil Science Society of AmericaEstados Unidos, 2022-02-11)
Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ...
Greenhouse gas emissions from beef grazing systems in semi-arid rangelands of central Argentina
(MDPI, 2018-11)
The livestock sector can be a major contributor to the mitigation of greenhouse gas (GHG) emissions. Within the sector, beef production produces the largest proportion of the livestock sector’s direct emissions. The objective ...

South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning
(Wiley, 2022-12)
Livestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns ...
Temporal variation of stocking rate and primary production in the face of drought and land use change
(Elsevier, 2020-02)
Rangeland stocking rate is subjected to opposite forces. On the one hand, it is expected to fluctuate with interannual variations of aboveground net primary production (ANPP). On the other hand, it is expected to be ...
